The second-order hyperfine perturbation of the optical isotope shift and hyperfine structure in Nd I

Year: 1990

Type: article

Abstract: Isotope shifts and hyperfine structures of six excited levels between 17790 cm -1 and 21346 cm -1 in Nd I were measured by means of atomic-beam-laser spectroscopy. Anomalies caused by the second-order hyperfine perturbation between two close-lying levels were studied for 143 Nd and 145 Nd. It was found that the anomalous energy shifts were caused predominantly by the second-order dipole-dipole hyperfine perturbation and that the contributions of the dipole-quadrupole and the quadrupole-quadrupole perturbations were negligibly small.
